综合护理干预对妊娠高血压综合征患者血压及妊娠结局的影响

目的探讨综合护理干预对妊娠高血压综合征患者血压及妊娠结局的影响。方法选取2012年6月至2015年2月来江西省新余市中医院接受治疗的88例PIH患者作为研究对象。按照入院顺序抽签后随机分为实验组和对照组,对照组患者进行常规护理。实验组患者在对照组护理的基础上,进行综合护理干预。观察患者血压、分娩方式结局、胎儿结局。结果实验组护理后收缩压和舒张压均低于对照组和护理前(P0.05)。实验组早产、产后出血、胎盘早剥、剖宫产总发生率均低于对照组(P0.05)。实验组胎儿窘迫、新生儿窒息总发生率均低于对照组(P0.05)。结论综合护理干预能够降低妊娠高血压综合征患者的血压,改善妊娠结局。

Normal and pathological color characteristics of human blood components

We have determined the averaged absorption spectra in the near UV and visible regions of the electromagnetic spectrum for aqueous solutions of hemolyzed blood, plasma, and serum from 100 donors and 95 patients with different diagnoses and different severity of their conditions. From the averaged absorption spectra, we calculated the color characteristics of the hemolyzed blood, plasma, and serum from the donors and patients by the standard CIE procedure. The blood is considered as a single, indivisible light-absorbing system in studying complex biological specimens. __________ Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 73, No. 2, pp. 220–224, March–April, 2006.     

冠心病患者血清钙、镁、铁、铜、铬、铝变化的临床观察

观察血清钙、镁、铁、铜、铬、铝与不同类型冠心病的关系,将冠心病患者分为三组:(1)冠状动脉痉挛30例;(2)稳定型心绞痛(SAP)患者27例;(3)急性冠脉综合症(ACS)患者35例,以34例健康者为对照组(NC),利用ICP-AES法测定了其血清钙、镁、铁、铜、铬、铝。结果表明,与正常对照组比较,钙水平在冠状动脉痉挛组和稳定型心绞痛组偏低(P<0.05或P<0.01),男性急性冠脉综合症组血清铝偏低(P<0.05)。提示血清钙水平下降可能与稳定型心绞痛及冠状动脉痉挛有关,而男性血清铝水平下降可能与急性冠脉综合症有关。     

关于硒缺乏症,硒与透析的探讨

就硒缺乏症、硒与透析的关系，检查了慢性肾功不全患者血清中的硒，其浓度为９．８±１．９μｇ／ｄＬ，正常人的血清中，硒浓度为１３．７±２．６μｇ／ｄＬ．并对慢性肾功不全的患者进行透析，测定其血清中硒浓度为１０．７±３．１μｇ／ｄＬ．结果表明：慢性肾功不全患者血清中硒浓度低于正常人血清中画浓度，经透析后血清中硒浓度虽有上升，但仍不如正常人，并且随着透析期间的延长血清中硒浓度逐渐下降．

Direct determination of selenium in whole blood by anodic stripping voltammetry

Trace quantities of selenium can be determined in the presence of iron, copper and lead using anodic stripping voltammetry, depositing at –0.60 V in 0.1M HClO₄ and stripping in the anodic direction. Two separate peaks are observed at –0.25 V and –0.10 V belonging to copper and selenium, respectively. Sometimes one peak may be observed for both copper and selenium. In this case one more stripping (without deposition) must be done to obtain separate peaks. After standard addition, two strippings have to be done also. With this proposed method, 10^–7 M selenium could be determined as (1.09±0.03) × 10^–7 M with a 90% confidence interval in blood samples without any separation.Presented at Xth National Chemistry Congress, Bursa, Turkey, September 19–21, 1994

采用等温滴定量热法研究植物凝集素(PHA)作用于20%家兔血红细胞(RBC)的凝集反应过程, 以生物热动力学参数表达凝集反应动力学特征. 结果表明, PHA与家兔血红细胞凝集反应的平衡常数K为3.24×10⁵ L•mol^－1, 反应焓变( )为－238.548 kJ•mol^－1, 反应自由能( )为－32.722 kJ•mol^－1, 反应熵变( )为－0.664 kJ•mol^－1•K^－1. 反应为放热反应(Q＞0), 可自发进行(ΔG＜0), 反应为焓驱动、熵减过程(ΔH＜0, ΔS＜0, |ΔH|＞|TΔS|), 由化学键合作用、氢键和范德华力推动, 反应体系最终处于稳定有序状态. 所建立的微量量热法可以客观表征凝集反应的热动力学过程, 也为其他抗原抗体类型反应的过程评价方法提供新的技术参考.     

Numerical simulation of the process of autoregulation of the arterial blood flow

For describing the autoregulation of the blood flow in an artery under constant transmural pressure a mathematical model that takes into account the multilayer structure of the arterial wall, the diffusion and kinetic processes in the wall, and the nonlinear viscoelastic properties of the wall material is proposed. The limiting case of a thin-walled artery is studied analytically. The arterial-wall viscosity range on which the equilibrium state of the system is stable is estimated. Accurate stationary distributions of the nitric oxide, calcium and myosin concentrations in the arterial wall are found. Numerical simulation of the autoregulation process demonstrated the possibility of arterial adaptation to radius perturbations, the existence of slow oscillations, and system transition to a new equilibrium state with change in blood flow level. The results are in good agreement with the experimental data.
